Arrange cups in 13x9x2-inch metal baking pan. Pour enough hot water into baking pan to come halfway up sides of cups. Bake flans until just set in center, about 50 minutes. Remove cups from water & let stand 30 minutes. Chill until cold, at least 4 hours & up to 1 day. Cut around sides of each cup to loosen flan; turn out onto plate.
